The final flaw only affects Mac OS X and allows an attacker to crash Firefox with a malformed GIF file, potentially gaining the ability to execute arbitrary code on the victim's computer. This vulnerability is not present in Firefox 2.

The non-security fixes include an issue where the phishing and malware database did not update on first launch and a problem that could cause Firefox to not save the security certificate exceptions list properly. A bug that could result in missing output when printing a selection from a page (bug 433373) was resolved and a Linux issue causing Firefox to always start in offline mode when using a PPP connection (bug 424626) was also fixed. The Public Suffix list has also been updated (bug 438585).

Finally found my bookmarks by clicking on the 'up' arrow on the right side of the selection box, and not the drop down arrow that gave me a blank section showing nothing. Bookmarks also will not alphabetize or "sort by name."

Upon turning PC off or going on stand-by a pop up waring appears notifying me of an unknown program not responding. Then having to click another pop-up to save my sessions and close.

Faster Fox and other add-ons are not compatible with 3.

I dunno, I liked the previous FF just fine and had no problems at all. I also guess it would be a pain to try to go back to the older FF when everything functioned just fine without a hitch. Any patches to cure these issues? LOL
